LGUlS W. SCHREIBER, OF BEE, NEBRASKA.

GRAIN-DOOR FOR CARS.

To all wir/0771, it Hefty con/cern:

Be it known that l, LOUIS W. SCHREIBER., a citizen of the United States, residing at Bee, in the county of Seward and State of Ne` braska, have invented certain new and useful Ido hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable vothers skilled in the art to which it appertains to make and use the same. l

My invention relates to grain-doors for.

cars,I and has for its object to improve the saine in the several particulars hereinafterl noted.

The invention consists of the novel-devices and combinations of devices hereinafter described, and defined in the claims.

Inl the accompanying drawings, which illustrate the invention, like characters indiview in side elevation, showing the central sections of the door are forced under u of the said door-jambe.

portion of thel body of an ordinary box-car and showing my improved grain-door applied to one of the side door-openings thereof. Fig.' 2 isa transverse vertical section taken on the line :c2 x2 of Fig. 1, some parts vbeing broken away. Fig. 3 is a vertical section taken on the line x3 fc3 of Fig. 2'; and Fig. 4 is a detail in end elevation, showing the irnproved grain-door removed from working position and folded.

The numeral 1 indicates the body of a beX- car, Athe same having the usual side dooropenings 2 on each side thereof. The vertical' sides of the-door-framework areon their inner portions cut back or rabbeted at 3 4 tov form seats respectively for the upper and lower sections of the-graindoor and to form heavy stop-flanges 5, against which the salild t e pressure ofthe grain.

The grain-door is made up chiefly. of an `upper section 6.and a lower section 7, which parts are connected by hinges 8. The upper section 6 has downwardly-converging` end surfaces, and the lower portions of the seats 3 in the door-jambs are formed witluco'rrespondinglyconverging surfaces 3, as best ward between and clear of the stop-flanges 5 Keeper-plates 9, secured to the inner surfaces of the door-jambs,' serve tol hold the upper door-sections 6 i Specification of Letters Patent.

against inward movement when it is in work ing position. Stop-plates 1() are slidably connected to the ends of the lower doorfsections 7, as shown, by means of slotandpin` connections 11. These stop-plates 10 are provided with arms 12, that are pivotally connected to a lever 13, which lever is pivoted to the door-sections 7 at a point beindicated at 1.4. The lever 13 is made in two by a hinge 15, that stands in line with the door-hinges 8. The upper 'end of the lever 13 is held to the upper door-section 6 by a guide-yoke 16. An ap roximately rectanandis adapted to be turned over the upper end of the said lever to lock the tw leversections togetherwhen the door-sections are folded, as shown in Fig. 4.

When the door is applied as shown in Fig. 1 and the vstop-plates.lOare moved inward, as shown by full lines in said view, the lower thereby to allow the grain to eely run from the ,car without removal of the grain-door and without requiring any part of the door \section to be moved vertically upward while it is subject to grain-pressure. i

Thefol'ded door may then be raised upward until -its upper edge engages the pivot-pins 21 whereupon it may be swung inward and upward on the said pins int-o the position shown When the folded the link 22 ma be connected to the hook-lug 23, and the fol ed door may thenbe suspended in that position by the said link and by the fingers 20,`which then rest upon the pivotpins 21.

The improved grainfdoor above described while of small cost may be very easily operated and is not liable to be broken in opening the car for the removal of the grain. It is a well-knownfact that grain-doors as usually constructed are` broken or damaged to a very considerable extent every time a car loaded with grain is opened up.
